Cor ros ion Corrosion can also affect bowl parts made of stainless steel. This corrosion can beflat-spread or pit- or crack-shaped and merits special attention,

Corrosion on stainless steel bowl material should be examined thoroughly and do-cumented.

Flat-spread corrosion can usually be measured (reduction of wall thickness)

Pit- or crack-shaped corrosion cannot be measured without the risk of damage. Atthe ini t ia l stage pi t-shaped corrosion is general ly caused by chlor ine ions.

Depending on the stressing of the part, pit-shaped corrosion can result in crack-shaoed corrosion.

Possible formation of pit-shaped corro-s ron .

Fig. 34

Such pittings can only be investigated by a materials expert,

In case of crack-shaped corrosion aftack with or without superposed flat-spreadand pi t-shaped corrosion on main bowl components, the machine must be shutdown im m ed ia te ly .

1 . 7 E r o s i o n Erosion is caused by solid particles in the process tiquid.These solid particles grind marks into the surfaces with which they come i-:c con-t a u t .

The following factors favour the occurrence of erosion:

. hard solids particles

. high throughput capacit ies

The f i rst s igns of erosion should be careful ly observed and documented. Erosioncan deepen rapidly, thereby weakening the bowl material.

Contact your nearest Westfalia Separator representative for a thorough examrn-ation Information on the nature of the damage can be provided by photos plastercasts or lead molds

The surfaces most susceptible to erosion are

1) the bottom of the distr ibutor. the r is ing channels and the r ibs

2) the centripetal pump (cavitation)

3) all surfaces in the area of the solids discharge ports,

4\ the nozzles.

l g p l i c a t i o n The separators OSC . , -0136-. and OSC . . -s6-, . . wi th UNTTROL systemr are eQuipped with a self-cleaning disk-type bowt and' are applied for clarification and purification in fueloil (up to a density of 1 .0'l g/ml)

and lube oi l t reatment olants.

The centrifuges of the c -Generation are equipped with a "soft-stream-inlet system,,for gentle product treatment. This results in optimum separating efficienly andhi gher specif ic capacit ies,The patented HydroStop system enables controlled bowlejections to be performedat full operating speed, The centrifuges operate without regulating rings,

The centrifuges with uNlrRoL system are provided with two basic monitoring sys-tems:r Water content monitoring system - WMS. Sludge space monitor ing system - SMS

,,separation" means the separation of liquid mixtures which consist of two liquids.with simultaneous removal of the solids contained in the liquids.

, ,Clar i f icat ion" is the removal of sol ids from a l iouid.

The most important component of the centrifuge is the bowl. Depending on the ap-pl icat ion, the bowl of design -0136- can be assembled to ooerateo as clarifier/purifier bowt (WMS) or. as clar i f ier bowlwith sel f- thinker controlsystem (SMS)

Conversion of the clarifier/purifier bowl into a clarifier bowl with self-thinker controlsystem and vice versa can be carried out quickly and easily.

Prerequisite for treatment technology (separation) is that the components of theproduct

- can be separated mechanically- have different densities and- do not emulsify.

A separator is characterized by the bowl for a specific applicati0n. Before comingto the particulars of the bowl the general operating principles of the separator areexolained first

Liouid mixtures or liouid-solids mixtures can be seoarated- in the gravitational field of the settling tank or- in the centrifugal field of the separator,

orovided the constituents of the products have different densities.

As the centrif ugal field of the separator is extremely more effective than the gravita-tionalfield of the settling tank. centrifugal separation in the separator is much fasterthan separation in the settling tank.

A l iquid mixture of l ight and heavy phases, e.g. oi l - water, iS separated into i ts c0n-stituents in the disc stack of the purifier bowl.

The disc stack consists of a large number of conical discs placed one above theother. Each disc is provided with Spacers which ensure precisely determined nar-row disc interspaces.

The entire separation chamber therefore consists of many parallelly arranged inter-spaces of low height, thus reducing the radial sett l ing distance for the sol tds.

The sol idso settle on the underside of the disc above and

. sl ide down into the sol ids holding space.The smooth disc surfaces favour sl id ing down of the sol ids and ̂ en ce sel f-c lean-ing of the discs.

After starting the separator, the shut-off device for operating liquid is actuated bymeans of the control uni t .

The operat ing l iquidr flows into the injection chamber of the bowl bottom and. from there through inlet holes into the closing chamber.

By this means closing of the bowl is initiated.

The annular piston. moves into closed position.

The l iquid pressure in the closing chamber. r ises the sl id ing piston,r presses the sliding piston against the gasket of the bowl bottom, thus

The liquid is peeled off by the centripetal pump and flows into its spirat channetsfrom outside, its kinetic energy being converted into pressure energy which is ca-pable of discharging the l iquid under pressure.

At a low backpressure the depth of immersion of the centr ipetal pump is smal l , l tcan, however, be increased by throttling the valve in the discharge tine. By thismeans it is oossible to obtain

- a good l iquid seal,- an air- and foamfree product,- a higher backpressure.

The separator is driven by a standard motor, type 85.Power transmission to the bowl spindle is effected via a centrifugal clutch to theworm wheel shaft and from there via a worm gear where the worm wheel is the driv-ing member and the worm the dr iven member. Simultaneously the mounted gearpump is driven by the worm wheel shaft via a safety clutch

The centrifugal clutchr gradual ly br ings the bowlto i ts rated speed. eliminating premature wear on gear parts and on the motor,

The start ing current and the accelerat ion t ime can be regulated by the number ofclutch shoes inserted.

Optimum dewatering of oils containing water is only possible if the bowl is correctlyadjusted to the difference in density between the oil and the water.

The regulat ing r ing with the correct inner diameter, i .e. with the diameter that corre-sponds to the density difference between the oil and water, should therefore be se-lected from the set of regulating rings (with different inner diameters) supplied withthe separator and fitted in the bowl.

The inner diameter of the regulating ring to be selected can be determined by ex-oeriment. The rule of thumb is:r smal l regu la t ing r ing fo r heavy o i l ,r la rge regu la t ing r ing fo r l igh t o i l .

To avoid emulsification, begin the test by inserting a large diameter regulating ringand then switch t0 the next smallest.

l f the regulat ing r ing is too large,- the water discharging through the water outlet will contain oil.

l f the regulat ing r ing is too sm al l ,- s l ight emulsi f icat ion wi l l occur or- the 0il discharging through the clean oil outlet will contain water,

The milky or dirty appearance of the water is quite normal: it is caused by the oilwasnrng process.

A separating zone between the light and heavy liquid forms in the bowl; the centreof this zone is the separat ing l ine.lf the correct regulating ring has been selected, the separating line will be positionedat the outer rim of the discs.

After opening the bowl, the separating line between water and oil. which is normallyfound on the underside of the separating disc, will indicate the position of the separ-at ing zone.

Take note of the following sections:

The best separation efficiency is achieved with lowest viscosity of the product tobe seoarated.In the case of non-conforming products,

- refer to the sales documents or- consult the manufacturer.

In the case of emulsified oil the separating temperature must be increased.

lf an oil pre-heater is used, a temperature controller (thermostat) must befitted. Thetemperature of the feed product must be displayed on a screwed-in thermometer.

The centr i fuge- can be converted into a purifier without self-thinker control system with the aid

of a conversion kit (see sect. 2.5)- and can then be applied in the first separation stage.

The operating mode of the control unit must be switched to "Separation" so that thebowl is supplied with the sealing water necessary for purifiers. The water seal whichprevents the oil from discharging through the water outlet must be maintained dur-ing separatron.

The centrifugal clarifier is equipped with the self-thinker control System as a stan-dard feature.

The clarifier bowl may not be supplied wrth water (exception: checking the self-

thinker funct ion and during displacement),The operating mode "Clarifying" must therefore be switched on the control unit. This

automatical ly suppresses the f i l l ing process.

The clarifier bowl with self-thinker control system serves to polish the products in

the second separation stage while at the same time executing a monitoring f unction

and solids-dependent solids ejection control of the entire system.The centrifuge therefore carries out a quality check of the different products.

The bowl is ejected at full bowl speed by automatic actuation of the solenoid valves

for operating water.

In the clarifier operating mode with self-thinker control system the ejection time iS

determined by the level of solids in the bowl

lf the centrifuge is operated as a conventional purifier, the ejection time must be

determined by calculation or graphically (see 3.5). The determined separating timeparameter must be set on the control unit.

D i s p l a c e m e n t

When separating, the loss of feed liquid unavoidable during ejection. can be re-

duced to a minimum by displacing the feed liquid with water before sludge ejec-

tion takes place This is of special importance when processing valuable feed

l iqu id .

The duration of the displacement liquid supply has to be determined by experi-

ment.

. l f the t tme of displacement is too long, displacement l iquid wi l l d ischarge from

the l ight l iquid out let

o l f the t ime of displacement is too short , part of the valuable feed l iquid wi l l re-

main in the bowl and then be ejected during ejection.

r Disptacement of the light liquid can also be accomplished by throttling the valve

in the discharge l ine for heavy l iquid.

F lu sh e jec t ion

lf the solids are firmly stuck to the wall and cannot be ejected- due to an excessively long dwell time or- due to the solids Properties,

either the separating time must be shortened or a f lush ejection must be carried out

after a total ejection by fil l ing the bowl with water or product, and emptying it again

P r o g r a m c o n t r o l

. Displacement, ejection and flush ejections at precisely defined intervals are best

carried out with the automatic control unit.

o The clean oil discharge and water discharge can be monitored'

o Faults can be signalled optically or acoustically.

The separator is driven by a three-phase AC motor via a centrifugal clutch.The specified motor ratings are minimum values which have been specified underconsideration of the starting current. Since the current consumption of the motordrops after start-up, overtoading of the motor during operation is not possible.

The start ing t ime depends on the- moment of inertia of the bowl,- number of clutch shoes used,- condition of the clutch shoes,

The starting current can reach 1.9 - ztimes the value of the rated currenr (seestart-up diagram). This is to be considered when dimensioning switches, tead-inwires and fuses.

The motor- can be started across the line,- has to be protected against undue temperature rise either by thermal releases

or by means of a device which ensures f ull motor protection

Protection of the motor by means of thermal releases has to be ensured as follows:- during operation, by a release adjusted to the rated current and- during start-up by means of a release adjusted to 1 .8 times the value of the

rated currentThe release adjusted to the rated current must be bridged during the startingi lme.

Full motor protection can only be ensured when PTC resistor type temperaturefeelers are incorporated in the winding of the motor.

N o t e :

r The temperature feelers must be connected to a commercially available trippingdevice,

r Externalvol tage higher than 2.5 vol ts must not be appl ied to the terminals of the

temperature feelers.

. When testing for continuity do not use a test lamp but only an ohmmeter.

The motor must not be switched on be-fore the gear chamber is fil led with oilOil level must be up to upper third ofsight glass.

The gear oil designated "Separator lube oil CLP 220" tested by Westfalia SeparatorAG meets the requirements and should preferably be used (see attached table oflubr icants).

The viscosity class SAE 40, 50, 90 covers a larger viscosity range than that statedabove. However, the oils used for the lubrication of the separator may only havethe viscosity specified above.

EP oils (oils with high pressure additives) may only be used, if they have no corros-ive effect on copper base alloys (see attached table 0f lubricants)For re-greasing the motor bearings, refer t0 the instructi0ns 0f the motor manufac-IUrer.

The centrifugal clutch- serves for power transmission between motor and gear,- gradual ly br ings the bowl up t0 i ts rated speed,- eliminates premature wear on gear parts and motor.

The starting time can be regulated by the number of clutch shoes.

The sm al ler the number of c lutch shoes used,- the lower the friction moment,- the longer the start ing t ime,- the less the wear on gear parts and motor.

Only 2,3. 4 or 6 clutch shoes may be evenly distributed in the clutch driver. Thenumber of clutch shoes to be used depends on whether the motor power has to belower or higher.

Note that the driving effect will improve after several starts.

Smoking of the clutch during the first few starts is normal and will disappear aftera short time of ooeratron.

lf the bowl comes up t0 rated speed inless than 5 minutes (see name-plate).the motorwil l pul l too high astart ing cur-rent (1..* > 1 ,8 x lp). This condit ion canbe easily overcome. by reducing the number of clutch

shoes to 4 or 3.o Ensure equal distr ibution of thq

clutch shoes.

1 9 0F ig.

Wear to the clutch shoes depends on thenumber of start-ups,- ejection frequency.

Check condition of clutch Shoes from time to time (See "Lubrication and mainte--ance schedule")

The clutch shoes must be replaced in good t ime (before the l in ings are w0. 'down to the base material), to avoid damage to the contact surf ace ol clutch rin;

such damage would result in premature wear of the clutch shoe linings.

Replace always all the clutch Shoes at the Same time, to avoid unbalance,

Optimum dewatering of oils containing water is only possible if the bowl is correcilyadjusted to the difference in density between the oii and the water.The regulating ring with the correct inner diameter, i,e with the diameter that corre-sponds to the density difference between the oil and water, should therefore be se-lected from the set of regulating rings (with different inner diameters) supptied withthe separator and fitted in the bowl.

The inner diameter of the regulating ring to be selected can be determined with theaid 0f the diagram or by experiment. The rule of thumb is:r smal l regu la t ing r ing fo r heavy o i l ,. la rge regu la t ing r ing fo r t ighr o i t .

The diagram can be used to determine- the inner diameter of the regulat ing r ing ano.- if desired the density of the oil

for a given separating temperature. provided that the densitypf the oil is known ata temperature between 15 oC and g0 oC.

E x a m p l e

\l f no regulat ing r ing with the determined inner diameter is avaitable, a smaler r ingcan be machined to the required size. Before doing that, however, check biexperiment whether the regulating rings furnished withihe separator are adequatefor optimum dewatering. Experience has shown that the regutating rings suppiiedare normally adequate.

To avoid emulsification, begin the test by inserting a large diameter regulating ringand then switch to the next smaller.

l f the regu la t ing r ing is too ta rge ,- the water discharging through the water ouilet will contain oil.

l f the regulat ing r ing is too sm ai l ,- s l ight emulsi f icat ion wi l l occur or- the oi l discharging through the clean oi t ouf let wi l l contain water.

The milky or dirty appearance of the water is quite normal: it is caused by the oilwasnrng process.

A separating zone between the light and heavy liquid forms in the bowl; the centreof this zone is the separat ing l ine.lf the correct regulating ring has been selected, the separating line will be positionedat the outer rim of the discs.

After opening the bowl, the separating line between water and oil, which is normallyfound on the underside of the separating disc, will indicate the position of the sepai-at ing zone.

As a result of the deterioration in quality of fuel oils, the danger has arisen that the heavy oils used on boardcontain greater amounts of substances injurious to health.lhese include: '

.- polycyclic aromatic hydrocarbons,- lead compounds,- chemical residues,

An increased amount of polycyclic aromatic hydrocarbons is also present in used lube oils (waste oils)The health hazards for the engine room staff depend to a large extento on the concentratiOns of the dangerous substances,o the ambient air ( inhalat ion of oi lvapours/oi lmist) ,. the intensity and duration of the contact with the skin or mucous membrane.

Possible sh orr-rerm effects:r headaches,. dizziness,. nausea,r i tching or burning of the skin,

Possible lon g-term effects:r al lergic react ions, especial ly skin al lergies,. festering inflammation of the skin pores (oil-acne).. damage to the central nervous system after inhalation over a long perroo.. skin cdncer caused by direct skin contact over a long period,. Lung cancer or cancer of the digestive organs after inhalation over a long period \

(not certain as the causes are difficult to separate from the effects of smot<ing and alcohot;.

Code o f p rac t ice and persona l p ro tec t ive measures :. Avoid skin contact with heavy oils or lube oils if possiblel

- Wear suitable protective gloves.- Apply a protective ointment to the skin (e.g. ointment no, z6), especially if no protective gtoves are

worn!o Avoid breathing in oil vapours if possibler. l f possible. improve the air c irculat ion in the rooml

Ful ly open the air regulat ion f laps in the out lets of the air supply ducts ' in the centr i fuge and f i t ter area.. Wash affected areas of skin frequenily and thoroughly!

Apply protective ointment to the skinl' Personal hygiene is of the utmost importancel. Change dir ty overal ls regular ly!' Exercise special care when carrying out maintenance work on and cleaning heavy oil and lube oil centri-
